摘要：

Dynamics of zonal flow excitation in tokamak plasmas is investigated based on the resistive interchange mode turbulence. Employing low-freedom approach, the resistive interchange mode turbulence-zonal flow system is solved both analytically and numerically. Our results show that the large-scale zonal flow or oscillating zonal flow can be excited in the case of sufficiently high pressure gradient (driving force).
